HAPPY RELEASE DAY: A Kiss of Blood (Vamp City #2) by Pamela Palmer

One
of the few humans who managed to escape the deadly twilight world of

When the handsome,

knows she can never trust him after the betrayal she suffered at his
hands. But with her beloved brother's fate hanging in the balance, and
her own power beginning to emerge, she chooses to risk all on yet
another perilous journey back to Vamp City. And though she tries to deny
it, her heart begins to hold hope that even a ruthless vampire can
learn the meaning of true love….
